IMPROVEMENT IN CHURNS Specification forming part of Letters Patent No. 143,919, dated October 21, 1873; application iled June 14, 1873.

To all whom it may concern:

Be it known that I, JOHN MASTEN, of Lee, in the county of Athens and State of Ohio, have inventeda new and valuable Improvement in Ohurns; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and toV the letters and figures of reference marked thereon.

Figure l of the drawings is a representation of my improved churn by a plan view. Fig. 2 is a vertical cent-ral section through the churn.

This invention has relation to churns; and it consists in the construction and novel arrangement of the oblique dasher-rods, inclined toward each other at the top, and from each other at the bottom, whereby thev dashers are better spaced, and accommodated in an ordinary tapering churn-barrel5 of the series of concavo conve-X vdisks on each rod, forming the dashers; of the bent crankarms, whereby the pitmen connecting with the dash-rods are brought `into the vertical position; and of the gearing and iiy-wheel, in connection with the double dash, as hereinafter more fully described.

In the. accompanying drawings, the letter A indicates a frame, on the floor of which a churn, B, of the Ordinary tapering form is placed. O O indicate the two dash-rods, inclined toward each other upward, and provided at their lower or divergent ends with the coneavo-convex disks c, arranged one above another, with the convex sides upward, and with sharply-beveled edges z directed somewhat downward--a form especially adapted for the rupture of the butter capsules or cells. The dash-rods O O' pass through the top of the churn, and above through a guide-stand, D, on the frame A. On the stand D journalseats are provided for the shafts ff' of the wheels G G', which gear with each other, and

' for the shaft of the large gear-wheel I, which cured the cranks F F', each of which is steadied on the end of its shaft by means of a stout thimble or collar, a, and is bent in its shank outward toward the dash-rods. The ends of these cranks are connected to the dash-rods by the pitmen E E', which are, by means of the bent cranks,

brought into the vertical position, thereby avoiding an offpressure, which would have a tendency to slant the dash-rods outward, creating undue friction, and interfering vwith the proper operation of the dashers.

The formation of the concavo-eonvex dasherdisks favorsthe rising of the same, and the introduction of air into the cream by their descent. The alternate up-and-down movement of the dashers prevents, in a great measure, the lifting and splashing, and at the same time creates a thorough agitation ofthe cream.

What I claim as new, and desire to secure by Letters Patent, is-

l. In a churn, the two dasher-rods O O', di verging fromeach other at their lower ends,

and provided with dashers c, and operated by alternate up-and-down strokes, substantially as specied.

2. The arrangement of the wheels I G G' with the bent cranks F F', and connecting-rods E E', working in a vertical plane, the fly H,

and the double dash-rods O C', all as herein
